As can be seen from the above, the pivoting module 100 of the present embodiment can cause the first curved surface 212 and the pushing surface 510 to clamp the pivoting shaft 310 by pushing the elastic member 400, thereby making the second component 300 and the first component. The 200 provides a suitable friction when rotating relative to each other. On the other hand, even if the rough structure 216 on the first curved surface 212 is worn after long-term use, the ejector of the elastic member 400 can continue to have sufficient positive between the pivot shaft 310 and the first curved surface 212. The force provides a frictional force, so the pivoting module 100 of the embodiment has good durability.
